D RAG SAW.

SPECIFICATION forming part of Letters Patent No. 415,764,:dated November 26, 1889.

Application filed May 27,1889. Serial No. 312,208. (No model.)

To all whom it may concern.-

Be it known that I, JOHN H. ALESLAGEL, a citizen of the United States, residing at Pyrmont, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Drag-Saws and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specifica; tion.

My invention relates to improvements in drag-saws, the several features of which will be fully hereinafter set forth.

In my invention the saw is driven by a gear to which is attached a fly-wheel, the machine being operated by a crank, and thereby giving a regular motion to said saw, and so connecting the same to the driving mechanism that the saw moves nearly on a plane, and does not oscillate greatly, as do some other forms of dragsaws.

The mechanism is illustrated in the accompanying drawings, in which Figure I is a side elevation of the machine. Fig. II is an enlarged transverse section on line m, Fig. I, showing the pitman-connection. Fig. III is a top view of the machine.

In all the views like letters designate like parts.

A is the frame, which may be constructed of iron or wood.- At the left end are two legs and the central horizontal slot 0. Near the center is a bearing for the shaft v. To the right of this is the spindle w, and at the right end is attached the angular piece 0, which serves as a guide to the saw, and has the point it to engage the log. The slotted adjustable guide B is bolted to the side of the frame. This serves as a guide for the saw-pitman D, and may be lowered as the saw penetrates the log. \Vhen the saw is not being operated, a pin is placed in the guide to hold up the saw-pitman. The supportingarm L is bolted to the side of the frame, and in the lower end is the bearing for the near end of the shaft 0), and the other end has its bearing in the frame. This arm has a corresponding part attached to the top of the frame, and these two parts form bearings for the spindle of the cog-wheel F. To this spindle is attached the crank G, used in operating the machine.

To the shaft v are attached two pinions of the same size. The one I-I (indicated by dotted lines) is between the arm L and the frame A, and the other II is external to the back of the frame. The former engages the cogwheel F and the latter the cog-wheel K. To this shaft, external to the supporting-arm, is attached the fly-wheel I. The pivotal bolt 2? moves within the slot of the frame, and to the rear end is attached the pitman or arm J, and the other end of said pitman is connected by a wrist-pin to the cog-wheel K. On the near end of the same is connected the saw-pitman D. \Vashers s s are used between the pitmen and the frame. To the end of the latter pitman is attached the saw E.

The circular dotted lines at M show the position of the log during the operation of sawing.

The operation is thus: The point at the end of the frame is driven into the timber, the pin withdrawn from the pitman-guide, and the mechanism is put into motion and the sawing proceeds. A handler could be attached to the fly-wheel, as shown in Fig. II, and thereby the wheel F, with its crank G, could be dispensed with. t

Having fully described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. In a drag-saw, the combination of frame A, having slot 0, cog-wheel F, pinion II on shaft 1), cog-wheel K to engage a pinion H on said shaft, fly-wheel I on said shaft, pitman J, pivotal bolt 25, and saw-pitman D, substantially as described.

2. In a drag-saw, the combination of frame A, having slot 0, fiy-wheel I, with handle,

pinion II and pinion H on shaft o, cog-wheel 5 K to engage the same, pitman J, pivotal bolt 2%, and saw-pitman D, substantially as described.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

JOHN H. ALESLAGEL.
